 """
 For creating a range of variables with numbers, (something
 like this: 'var0', or 'var_0') you do the following:
 ----------------------------------------------------------
 for key in range(9):
    globals()['key_{}'.format(key)] = 'a'
 ----------------------------------------------------------
 This will produce a set of variables, name thusly, 'key_0,
 'key_1' and so on, that will all have the value 'a'. But
 that can be easily changed.
